Add Repository và Update System

1. Add Dag RPM Repository for yum because that has many useful packages.

root@ns ~]#wget http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt

// When you use dag repository, Input yum command like below.

2. Update your system with 'yum' command. However, before doing it, Install 'yum-fastestmirror' that looks for fast server and download packages from there automatically when yum command is used.

root@ns ~]#yum -y install yum-fastestmirror
